Do we have any statistics comparing the results of games played by players X hundred points apart at different positions on the scale?
The information is in this article:https://en.chessbase.com/post/what-s-wr ... elo-system

Re: 4NCL Online

A quick question for Brian V - the histogram of FIDE ratings, given above, is it for English players only? (Since the ordinate axis only goes up to about 10,000 roughly the number of players in the ECF grading pool and no where near the number of all players in the FIDE rating pool.) It's all FIDE ...

Re: 4NCL Online

[Indeed - that is probably what a grading list produces]. Whenever a grading list is produced in graphical form, it invariably comes out looking Normal. The ECF one of Clarke grades peaks at around the 135 to 140 area. Whilst it's plausible for the upper end to be Normal or have a strong resemblanc...

Re: Could everyone lose their grade

The rules for grades will be changed in September to support monthly grading. We are still on track to deliver these on time. Everyone who has had at least one grade (separately for standard and rapid) published since 2017 will have a 4-digit grade for January 2020 when our monthly calculations will...

Re: July 2020 grades

The Chessnuts basic system is robust enough to handle Elo grades quite well. A little modification has been required but it churns out 4 digit grades exactly as specified.

Re: COVid19-What's wrong with UK?

However, we do not know how different countries count the deaths (whether all sources, or hospitals only), so comparison with other countries is pointless at present. I'm surprised that my fellow Old Reigatian Keir Starmer doesn't watch the daily press conference, or he would know that. [snip] i'm ...

Re: Has anyone figured out how to make a living?

The FT had an article in Saturday's edition on tennis earnings. The 250th ranked man won $124,000 in 2019 (womens 250th: $80,000). One needs to add on endorsements and deduct competition costs. The gist was how skewed the distribution was. Nadal won most with $16.4m. By eye on their graph about 50 p...

Re: 4NCL Online

I expect to have a summary of my further investigations on the ecf website by next week. I would point out that seniors in 2013 (the data are from that year) includes all players over 18, many still improving. Also many seniors will no longer be active on one of the list so missing in 2020. It is pl...

Re: 4NCL Online

I'm sure this topic must have been worked to death elsewhere but, when I've managed an OTB 4NCL team, it has almost always been the case that the conversions resulting from the {7.5 x ECF} + 700 formula result, at any rate for those below ELO2000, in higher [sometimes significantly higher] figures ...

Here's some unreliable tables
My fading memory as an occasional match supporter of my next door neighbour's team was that the team (in the Reading Combination) ended up playing nearly every day in April to complete their fixtures. But that's probably more unreliable than your source.

Re: Continuing Leagues & Established Events Online

This facility is, or will be very soon, in place. It is/will be available for teams who are all ECF members. While I understand there is nothing to stop matches taking place, we are still settling any special playing rules and how to handle standard play grading (internet results will not be intermi...

Re: World Senior Team Championships, Prague, March 2020

Without wishing to spoil anything, keep an eye out for the England Women as well. Sheila Jackson's finales in the last two round have made pleasant watching!
